medium Nessus Plugin ID 67224

Language:

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

William (B.J.) Snow Orvis discovered that Ruby incorrectly verified the hostname in SSL certificates. An attacker could trick Ruby into trusting a rogue server certificate, which was signed by a trusted certificate authority, to perform a man-in-the-middle attack.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
